Sažetak
The aim of the study was to evaluate the effect of natural zeolites on total nitrogen concentration in pig slurry. The study was carried out in an intensive pig farm in 3 equal fattening units during final 2 months of the pig fattening. Unit 1 served as a control. In unit 2 the commercial preparation, a natural zeolite, was added at the animal feed mix. In unit 3 the commercial preparation, the natural zeolite, was daily uniformly spread over the partially slatted floor of the fattening unit. Slurry samples were collected every 10th day during the investigated period. The total nitrogen concentration was analyzed using standard laboratory method. Study results demonstrated the total nitrogen concentration to be lower in both experimental units as compared with the control unit. The total nitrogen concentration was also lower in the unit 3 treated with the slurry additive in relation with the unit 2 with the feed additive treatment.
